tact with-the surface of the plate 82.-. Two vertical rows of openings9O and 91' are 'formed in the portion 88, these openings being vertically spaced apart a certain distance. Formed in the plate 82 are slots92 and 93 which are arranged in pairs and in alignment with the rows of openings-90 and 91. Adapted to extend through each slot 92 and 93 and adjacent openings-90 and 91 are bolts 94. The'slots' and openings' are of the same arrangement and character-as" the slots and openings described in the first form of my" invention. a I v a v Secured to the flange 25 of the leg 15is a primary support in the form of a plate '96, The plate 96 has a' portion 97 and a portion 98, which The portion 98 is adapted to engage and formed in the end orthe channel 80 "is a pairof slots 101 which are vertically aligned and which are in alignment withthe row ofopenings 100. Adaptedto extend through each slot 101 and one ofthe openings -100'are'bolts 102. These openings and slots 100 and 101 bear the same relation to the slots '90 and 91 and 92 and 93 as do the pairs of openingsand slots in the first form of my invention.

Secured to the lower part of the portion 98 is an angle bracket 104. The anglebracket has' a horizontal leg 105 through which a jack screw 106 is extended. A head 10'] of thejack screw engages the lower face of the leg 105, and a clamp nut 108 isadvanced onto the jack screw 106 and engages the upper face of t.ie leg 105. Formed in horizontal flanges 110 of the channel 80 are vertically aligned openings 111 through which the jack screw extends. Engaging the lower face of the lower flange is a jack nut 112, and engaging the upper face of the upper flange 110 is a holddown nut 113. 2

This form of my invention is designed for girts which are spaced away from the legs of the derrick. In the form shown, thegirt is spaced a distance inside the derrick. It will be seen, however, that by inverting the parts and extending them in opposite directions it is possible to support the girt in a position outside the derrick.

The adjustment of. this form of the: invention and the features thereof are substantially the same as described with respect to the'first form of my invention. When the bolts 94 and 102 are loosened, the jack screw'may be operatedand the girt may be raised or lowered, as desired, it of course being understood that the hold-down nut 113 must be loosened before the jack nut is operated. The slots 92 and 93 and 101 permit the girt to slide vertically without removing the bolts, and if the distance the girt is to be moved is greater than the length of the slot the bolts maybe extended through different openings.

In Figs. 10 and 11 I show a third form of my invention which I will now describe.

Secured to the flange 23 of the leg 15 is a primary support having a plate. 120 which is secured in place by rivets 121. The right end of the plate 120 has a pair of angles ,122 secured thereto by rivets 123.. Attached to the angles 122 by bolts 125 is a bracket 126 through a horizontal 'fiange 127 of which jack screws 128 are extended.

Thejack screws 128 have headsl and have clamp nuts 131 which engage the horizontal leg 127 of the bracket'l26,'thus clamping the jack screws 128 securely thereto. The girt used in inclusive;

'1 to' 4 inclusive, the 'only'difference being that the flange ther'eof is longer,

so that the flange 36 is spaced in-a plane a distance 'to theoutside of the derrick and away from the flange 230i the leg 15. The flange 36, as illustrated in the first form of my invention,

is'providedwit the openings 54, and the end of the channel is provided with the slots 53. Bolts 'liavin'g lized. r i

This form as described is adapted for use where the girt is to be placed a short; distance outside the-derrick, but, by invert ing the parts and extending thesecondary mem ber 20 in the opposite direction, the girt 38 may be supported on the insideof the derrickleg 15.
